A pneumatic-snake like appratus and method for routine clearing of clogged plumbing-drain lines in buildings and marine installations, employing an air-supply of 80-120 psi at a nozzle-generated velocity sufficient to virtually disintegrate obstructions logged within the plumbing-drain system. Owing to direct-impact infusion of high-velocity air exiting the special ball-shaped fracturing-nozzle positioned at leading-end of the snaking air-hose, the “Pwr / Clogbuster™” is more effective at breaking-up plumbing-line clump-obstructions than conventional mechanical coiled-metal snake devices. Passed-into a drain-line to point of obstruction, the pneumatic-snake operator opens a control-valve positioned between the air-hose and air-supply unit (a conventional portable air-compressor / reservoir rig);—whereupon a few thrusting blasts at point-blank are sufficient to clear an obstruction. An annular drain-cup device is slip-fitted on the air-hose, and held near the drain-entry point, as to provide splash-deflection protection during the procedure;—plus, generic-variant nozzle configurations are also set forth.
